Description

The OB38A08T1is a 1T (one machine cycle per clock) single-chip 8-bit microcontroller. It has 8KB embeddedprogram memory, and executes all ASM51 instructions fully compatible with MCS-51.

OB38A08T1contains 512B on-chip RAM, up to14GPIOs (16L package), various serial interfaces and many peripheral functions as described below. It can be programmed via writers. Its on-chip ICE is convenient for users in verification during development stage.

The high performance of OB38A08T1can achieve complicated manipulation within short time. About one third of the instructions are pure 1T, and the average speed is 8 times of traditional 8051, the fastest one among all the 1T 51-series.Its excellent EMI and ESD characteristics are advantageous for many different applications.
